New Zealand assistant coach Ian Forster says Wales' poor display against England is viewed as a warning by the Kiwis for Saturday's first Test in Auckland.
Wales were outscored five tries to one in a 27-13 defeat by England at Twickenham on 29 May.
Foster told BBC Wales' Ross Harries the game showed "it's easy to be rusty in your first Test of the year - and this is our first Test of the year".
Wales have not beaten the All Blacks for nearly 63 years.
